We have our Service Desk system set up to send automated messages for 1)Acknowledgment of a ticket received via email 2) Updating (including assignments, categorizing, prioritizing etc) 3)Marked Resolved 4) Closed.

Our users have long complained about the number of automated responses they receive for each ticket.  Finally when I kept hearing the number 6, I did a test.  Each type of update, even though I do them at the same time, goes out as an additional message.  So when I edit the ticket and assign it and prioritize it then click save - 2 messages are sent.

Is this a bug or do I need to configure it differently?
